'Application January 19, 1335, Serial at." 2,580 r "1 3mm,. totes-2 This "invention pertains to new and useful lm-' provements in devices forheating and ventilating automobiles and has for one or its important objects to provide, inamanneras hereinafter set forth, a device of this character comprising a novel construction and arrangement through the medium of whichithe water-in the cooling heating medium, I Another very important object or, the invention is to provide an apparatus of the aforemensystem of the vehicle engine ;-is utilized -'as the tioned character comprising a novel construction and arrangement through the medium of which fresh, heated air from the atmosphere will": be introduced into the automobile, the invention further including novel means for regulating or controlling the temperature'of said air. 7 Still another important object or the invention is to provide a'heating apparatus'for motor vehicles which includes a combination and arrangement vof parts whereby the 1 same air may be recirculated if desired;

Other objects of the invention are to provide a heating-and ventilating apparatus for automobiles which will be comparatively simple in construction, strong, durable, highly e'iiicient and reliable in use; compact, and ,which ,may be manufacturedand installed at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and whe'reini- 1 Figure 1 .is a view in front elevation of an automobile heater and ventilator constructed in accordancewith the present invention.

Figure 2 is a view in-vertical section through the device.

Figure 3 is a view in horizontal section, taken substantially on the line 3-.-3 of Figure2.

Figure 4 is a horizontal sectional view, taken substantially on the line 4-4 of Figure 2.

Figure 5 is a vertical sectional view, taken substantially on the line 5-5 of Figure 2.

Figure 6 is a view in vertical longitudinalsection through a portion of an automobile body, showing the means for discharging air into the rear portion of said body. 7

Figure 7 is a detail view in perspective of the heater which is mounted in the rear portion of the body. a

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which" beenillustrated comprises a casing lof suitable materiaL-preferably metal, whichis secured by brackets 2 orthe like on the dash oard} beneath. the cowl l of the-automobile.

The reterence fnumerallt designates a-zportion 5 of the usualhood or bonnet of the automobile, v 6 designates the automobile windshieldbeneath which, as usual, is the instrument boarder panel "L. The cowl 4 is provided with the usual venwhlch. is provided with a..1o

tilating opening 8 hinged closure 9. a v l a The casing l is provided, in its upper portion, with a partition Ill providing a cold air compartme'nt ll' andan airheatingcompartment I2 I in saidcaslnBi Mounted in the compartment I2 isia suitable hot water heater or radiator l8 1 through which water circulates from the cooling system'of the engine (not shown) of the automobile. .J'I'he'top id of the casing i has formed tively.; The valves i1 and III are manually actu-' V ated through the medium of rods I9 which extend slidably through the, instrument board I of "the vehicle.

Mounted on the casing i is a hood 20 from which an air conduit 2| rises, said conduit it including an enlarged or flared'upper end portion 22 which is engaged with the cowl ventilator 8 for receiving air from the atmosphere when the closure 9 is in open position. A control valve' 23 is mounted in the conduit 2|. said control valve being actuated by a rod 24 which also extends slidably through the instrument board 1. Air inlet openings 25 are provided in the hood 20 and controlled by valves 26 which may be retained in set or adjusted position by friction or in any other suitable way. The purpose of the valves 26 will be presently set forth. Projecting from the front or the casing l is a circular extension 21 which provides a housing for a centrifugal fan 28 which is driven by an electric motor 29. A partition 30 is mounted in the compartment H adjacent the fan 28, said partition being provided with an opening SI for the ,c emns ll of'the partition :0 into the fan houlmeral II.

A conduit 34 is connected to the discharge 31 v 2 ing :1 from which said air'is expelled by the m1 laaswillbereadilyunderstoodboteoursethe tan It .draws the ail-through the device. However, movement oi' the air from the atmosphere through the device is materially assisted by the forward movement oi the vehicle. Should it be desired to introduce only heated air into the automobile, the valve I1 is closed and the valve II is opened, the air then passing through theradiator ll into the compartment Ii, then into the fan housing 21 from which it is expelled through the discharge 32. The. temperature or the air which is discharged into the automobile may be conveniently regulated as desired by properly adlusting the valves l1 and II in a manner to cause a portion of the air entering through the cowl ventilator 8 to pass directly into the chamber II and a portion of said air to pass through the radiator I: and then into the chamber u where it is mixed with the unheated air. Should'it'be desired to recirculate the same air through'the heater, the closure 9 of the cowl ventilator l is closed or, i! desired, the control-valve" may be closed. The valves 20 are then opened to permit the air trom'the interior of the automobilerto' enter the'hood 20 from which it passes intoeither ,orboth o! the compartments II and llo! the casing I. The water pipes which connect the radiator II to the-cooling system of the automobile-engine are designated bythe reference nu- 'and extends therefrom beneath the floor I8 01' the automobile body 38 to a heater ll which is preierably, but not necessarily, mounted adjacent the front seat SI of the automobile, as shown to ad 'thatehangesinthedetailsosoonstructionand vantage in Figure 6 oi the drawings. The heater 31 (see Figure 7) is provided with discharge open ings it which are preferably in the form of slots.

It is believed that the 'many advantages of a heater and ventilator i'or motor vehicles constructed in accordance with the present inven-,

tion will be readily understood, and although a preferred embodiment oi the invention is as illustrated and described, itis to be understood .ings therein, a valve controlled air intake eon- :iormprisingacasingsaidcasingincludingacold air inlet openings'therein, valves for controllinglo said openlngsfahood mountedonthecasingand with the atmosphere, said hood enclomng the valves, and a pump for drawing the air through the casingand discharging said air into the automobile, said compartments communil8 eating with eacheother.
